If sin a 2 1 then the value of cot a is
Web29 jul. 2024 · Proposition: If 0 < θ < 90 ∘, then sin(θ)2 + cos(θ)2 = 1. Proof: Using the notation in the definition above, set θ = A. [1] Starting on the left-hand side of the desired identity, the definitions of sine and cosine give sin(θ)2 + cos(θ)2 = (a c)2 + (b c)2. Expand this and simplify to get (a c)2 + (b c)2 = a2 c2 + b2 c2 = a2 + b2 c2. Web9 dec. 2024 · A Computer Science portal for geeks.
